BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a functional seat for use in aconventional baby carriage which is a means for carrying an infant,i.e., four-wheeled, three-wheeled, or two-wheeled carriage, and moreparticularly, to a seat for use in a baby carriage capable of protectingan infant against the cold for the winter season and staying the infantin the stable condition.

2. Background of the Related Art

Several baby carriages have been developed to more comfortably andconveniently carry an infant for outings. As an example, a baby carriageincludes a foldable frame having two pairs of front and rear wheels andbeing foldable to reduce its volume for convenient carrying and keepingit, and a seat having a backrest which can be set to the frame at aslope suitable to support the infant sitting or lying on the seat.

When an infant goes out of doors with the baby carriage, a separatefoldable canopy for shading light and sheltering from wind is installedon the frame to protect the infant from being directly exposed to theatmosphere in the summer season.

However, the canopy shields the infant from the wind in the winterseason, but there is no means for keeping the infant warm against a coldatmosphere.

In order to keep the infant warm, the infant should wear winter clothesor be covered with a blanket. In this case, such preparation iscumbersome, and if the infant goes out in the cold weather for a longtime, it threatens infant's health. In case of using the blanket, it isnot easy to fasten the safety belt provided in the baby carriage. If theinfant is not fixed by the safety belt, the safety carrying of theinfant is not secured.

Recently, since outdoor activity is increased without regard to thewinter season and the summer season. In particular, it is neededcold-proof equipment for the infant for the winter season.

Meanwhile, when the infant is moved with the baby carriage, the infantand a protector do not respond to each other. That is, the protectorpushes the baby carriage at a rear side, while the infant sits on theseat. Consequently, the infant sitting on the baby carriage alone feelsuneasy Therefore, the infant is emotionally unstable.

SUMMARY OF THE INVENTION

Accordingly, the present invention is directed to a seat for use in ababy carriage that substantially obviates one or more problems due tolimitations and disadvantages of the related art.

An object of the present invention is to provide a seat for use in ababy carriage having a seat plate, a backrest plate, and a plane heaterbuilt in the seat plate and the backrest plate for keeping an infantwarm for the winter season, thereby securing free outdoor activity.

Another object of the present invention is to provide a seat for use ina baby carriage having loudspeakers built in left and right sides of abackrest plate for outputting an audio signal so that an infant isemotionally stable.

Still another object of the present invention is to provide a seat foruse in a baby carriage having fastening bands on rear sides of abackrest plate and seat plate for fastening the seat to the babycarriage.

To achieve the object and other advantages, according to one aspect ofthe present invention, there is provided a seat for use in a babycarriage, the seat including a foldable frame having two pairs of frontand rear wheels and being foldable to reduce its volume for convenientcarrying and keeping, and a seat set to the frame at a slope suitable tosupport an infant sitting or lying on the seat, which includes a seatplate supporting hips of the infant, a backrest plate extended from oneside of the seat plate for supporting a back of the infant, the seatplate and the backrest plate being foldably engaged to each other,heating elements installed in the seat plate and the backrest plate forkeeping the infant warm, an elastic coupling element for coupling theseat plate and the backrest plate, and a pair of loudspeakers connectedto a sound apparatus built at upper positions of the backrest plate ofthe baby carriage, thereby protecting the infant against the coldweather and giving sense of stability to the infant.

It is to be understood that both the foregoing general description andthe following detailed description of the present invention areexemplary and explanatory and are intended to provide furtherexplanation of the invention as claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A preferred embodiment according to the present invention will now beexplained with reference to the accompanying drawings. FIGS. 1 and 2show a seat for use in a baby carriage according to the presentinvention.

The present invention relates to a functional seat for use in aconventional baby carriage 10 including a foldable frame 12 having twopairs of front and rear wheels 14 and being foldable to reduce itsvolume for convenient carrying and keeping it.

The frame 12 of the baby carriage 10 is additionally provided with aseat 20 which can be set to the frame at a slope suitable to support aninfant sitting or lying on the seat. The construction of the seat isimproved to secure free outdoor activity for the winter season and toallow the infant to feel the stable.

The seat 20 includes a seat plate 22 supporting the hips of the infantand a backrest plate 24 for supporting the back of the infant. The seatplate 22 and the backrest plate 24 are foldably engaged to each other bya coupling member 30 such as a rubber band having good elasticity.

The seat 20 has a desired shape so that it is generally used in the babycarriage 20 which is made in various sizes. The seat plate 22 is made ina heart shape when shown from a top side. The seat plate 22 has arecessed portion 22 a at a front center, and is adapted to be properlyinstalled on any construction of the frame 12 of the carriage 10.

The backrest plate 24 is made in a convex shape when shown from a frontside, and has a pair of bosses 24 a protruding from both sides of anupper portion, in which loudspeakers are built in the bosses 24 a.

The seat plate 22 and the backrest plate 24 are provided with fasteningholes 25 for fastening the seat 20 to the frame 10 by safety belts ofthe baby carriage.

The seat 20 is made of a material having impact resistance, waterresistance, and heat resistance, such as urethane.

Heating elements 26 and 28 are installed in the seat plate 22 and thebackrest plate 24. A plane heater is used as the heating element in thisembodiment.

The heating elements 26 and 28 are supplied with a power from arechargeable battery 23. Overheat of the heating elements is preventedby a temperature sensor 21, and the heating elements are set as atemperature suitable for the infant.

A pair of loudspeakers 32 are built in the both bosses 24 a of thebackrest plate 24. The loudspeakers receive an audio signal from a soundapparatus 34 mounted in a proper position of the baby carriage 10 tooutput the audio signal to the infant sitting on the baby carriage,thereby being helpful to the development of intelligence and sensitivityand giving the sense of stability. The sound apparatus 34 and theheating elements 26 and 28 are electrically connected to a controller 33so that the sound apparatus 34 and the heating elements 26 and 28 arecontrolled by the controller 33.

FIG. 3 is a rear view of the seat 20 according to the present invention.Fastening bands 36 and 38 having high elasticity are provided on therear sides of the seat plate 12 and the backrest plate 14 to fix theseat 20 to the frame 12.

With the above description, the seat for use in the baby carriageaccording to the present invention has the following advantages.

Since the plane heaters are built in the seat plate and the backrestplate for keeping the infant warm for the winter season, the infant canenjoy free outdoor activity.

Also, the loudspeakers built in left and right sides of the backrestplate for outputting the audio signal to the infant, thereby stimulatingbrain cells of the infant and thus being helpful to the development ofintelligence and sensitivity and giving the sense of stability.

Since the seat of the present invention has the fastening bands forfixing the seat to the frame of the baby carriage, the seat can beeasily used in a conventional baby carriage as an auxiliary means.

The forgoing embodiment is merely exemplary and is not to be construedas limiting the present invention. The present teachings can be readilyapplied to other types of apparatus. The description of the presentinvention is intended to be illustrative, and not to limit the scope ofthe claims. Many alternatives, modifications, and variations will beapparent to those skilled in the art.
